"A Flexible Regression Model for Count Data" - to be published in Annals of Applied Statistics

The paper introduces a neat regression setup for over- and under-dispersed count data, which generalized Poisson regression and logistic regression (yes, it can be applied to binary data!). The model is GLM-based and has lots of neat properties. Estimation is fast too.
You can find the paper at http://ssrn.com/abstract=1127359 and R code here. This is joint work with Kimberly Sellers.

Visit at Technion

I am currently visiting with Prof. Ayala Cohen, head of the statistics lab at the Technion (Israel Institute of Technology), and my PhD advisor.

My office is right at the center of the action of the IE&M faculty, and I am having endless dejavu moments from my 5 years of grad school here. So many familiar faces! Not only faculty, but also many old-timer staff, and even fellow students who are here in new roles.

The main adjustment is moving from "letter" to A4 size paper.
